As I am new to Dolphin, and thus not able to correctly use a Wiimote for gaming... I have a few questions...

I know I can use a Wiimote for gaming with Dolphin, and I have succesfully installed it via Bluetooth. While configuring Dolphin to use the Wiimote, it recognizes it, but I can't seem to pair with it.

Now is my most basic question:
Can I even use a Wiimote for a GameCube game like TLOZ: The Wind Waker?

If so, could anyone please explain in a little more detail than the tutorial on http://www.dolphin-emu.org on how to pair with it... As Dolphin only uses my keyboard as input, which I don't want. I also rather don't want to buy a computer compatible 360 gamepad as I already have 2 Wiimotes to my disposal...

My last question is if it is possible, do I still need the Infrared bar from the Wii to make it work...

You need the infrared bar for the pointer, but you can use the mouse instead. Still you would need to assign some buttons for commands such moving toward/from the screen. As for wiimote in GC games I've never tried it
